讨论了空间信息网(SIN)未来发展趋势并提出了一种新的故障自检测方法。目前关于空间信息网络的研究十分有限,尤其是故障检测方面。针对空间信息网络发展趋势介绍了一种新的空间信息网络体系结构并对该体系结构特点进行了详细的分析,在此基础上提出了一种基于有限状态机的故障自检测算法。该算法通过创建一个故障探测器使得各卫星节点之间可以通过信息交互完成故障检测任务。通过故障检测器,各状态之间有条件的转移最终得到检测结果。每个卫星节点都参与检测器的状态转移过程达到自检测的目的。利用MATLAB仿真工具对算法进行仿真,结果显示所提算法具有较好的性能。

Future development trend of SIN （Space Information Network） is discussed, and a novel fault self -diagnosis method proposed. Nowadays limited research is focused on SIN ,particularly in the field of fault diagnosis. In connection with the development tendency of SIN, a novel SIN architecture is introduced,and its characteristics also analyzed in detail. In light of this, a fault self-diagnosis algorithm based on finite-state machine is proposed. This algorithm ,with a newly-designed fault detector,enables various satellites nodes to complete fault detection via information interaction. Through fault detectors, conditional transfer of between the states is done, and the detection result finally acquired. Each satellite would participate in state transition process of the detectors and complete the self-diagnosis. MATLAB simulation indicates that the mentioned algorithm enjoys fairly good performance.
